Getting really tired of all the crying about prop locks and no official iOS. If it bothers you don't buy an Inspire. Pretty sure there are over 10,000 inspires out there now... As a best guess. Maybe five units had the props fly off, for whatever reason. Mine never did... and I don't know of anyone else who had the issue. There are some videos with incredibly aggressive maneuvers to show that they don't fly off. The prop locks are a free, simple, and easy to use safety blanket if you you are concerned. As for the iOS the app is easily available online and all it takes is a little effort to find and install. It works perfectly on the latest Apple devices. There is a legitimate concern at this point when and maybe even if the app will become official. It's been three weeks past the supposed fix date, with no official word coming from DJI.... Not a optimal practice keeping customers in the dark..... Until such time that the Android version continues to advance and all the the new bells and whistles are in that version there isn't an issue. If that happens a few months from now and no iOS is available I might have to spend another $250.00 to get an Android Tablet. An extra HC Battery costs $200.00. If you are using this for any serious flying you'll need a couple of them or three or four standard batteries.... So what's another $250.00. Point is that the Inspire is a pretty amazing piece of equipment. I won't be happy to have to spend another $250.00 bucks, but for me it's more than worth it as a cost of flying this amazing machine. If Go Pro or someone else builds a better mousetrap, then so be it, but for now there isn't anything close in this price range. I'm flying mine with an iPad Mini, WiFi only and having a ball.
